Sulfonylamino-substituted benzoylguanidines, a process for their preparation, their use as a medicament or diagnostic aid, and medicament containing them

A benzoylguanidine of the formula I ##STR7## in which:

• R(1) is an alkyl radical having 1, 2, 3, 4, 5, 6, 7 or 8 carbon atoms;
• R(2) is hydrogen or an alkyl radical having 1, 2, 3, 4, 5, 6, 7 or 8 carbon atoms;
• R(3) is hydrogen, --SR(25), --OR(25), --NR(25)R(26) or --CR(25)R(26)R(27);
• R(25) is hydrogen, an alkyl radical having 1, 2, 3, 4, 5, 6, 7 or 8 carbon atoms or phenyl, which is unsubstituted or substituted by 1-3 substituents selected from the group consisting of F, Cl, CF.sub.3, CH.sub.3, methoxy, hydroxyl, amino, methylamino and dimethylamino;
• or
• R(25) is a pyridyl or pyrrolyl radical, which is unsubstituted or substituted by 1-3 substituents selected from the group consisting of the group F, Cl, CF.sub.3, CH.sub.3, methoxy, hydroxyl, amino, methylamino and dimethylamino;
• R(26) and R(27) are, independently of one another, defined as R(25) or are hydrogen or an alkyl radical having 1, 2, 3, 4, 5, 6, 7 or 8 carbon atoms;
• R(4) is hydrogen, F, Cl, Br, I, OH, --C.tbd.N, CF.sub.3, an alkyl radical having 1, 2, 3, 4, 5, 6, 7 or 8 carbon atoms, or an alkenyl radical having 2, 3, 4, 5, 6, 7 or 8 carbon atoms;
• R(5) and R(6) are, independently of one another, hydrogen, an alkyl radical having 1, 2, 3 or 4 carbon atoms, F, Cl, --OR(32), --NR(33)R(34) or CF.sub.3 ;
• R(32), R(33) and R(34) are, independently of one another, hydrogen or alkyl having 1, 2, 3 or 4 carbon atoms;
• or a pharmaceutically acceptable salt thereof.
